Abstract

PROBLEM TO BE SOLVED: To prevent an abnormality in a human body such as vibration disease, lumbago or pain in the shoulder from occurring and thereby save on labor by installing handy electric bars in such a way that each of the bars can be positionally adjusted optionally and inserting vibration cylinders into a ready-mixed concrete in a concrete shuttering while vibrating the cylinders to cause the deforming along the vibration cylinders. SOLUTION: A concrete shuttering 4 fillted with a ready-mixed concrete is installed right below a defoaming device and the handy electric bars 1 are positioned forward/backward and to the right/left with the shuttering 4 using a motor 10 for traveling and a motor 11 for moving to the right/left. In addition, an inclinable frame is inclined to the slope of the shuttering 4 through driving a motor 12 for inclining to the right/left sides and a motor 13 for inclining to the forward/backward sides to fit all of the handy electric bars 1 to the shutterings 4. Further, the handy electric bards 1 installed in sliders 6 are changed to positions where the handy electric bars 1 do not interfere with partition plates by driving a pitch feed motor 14, an the vibration cylinders 3 of the handy electric bars 1 are gradually inserted into the ready-mixed concrete in the shuttering 4 while vibrating the vibration cylinders 3 of the handy electric bars 1 with the use of the motor 15 for moving vertically. Thus it is possible to remove foams along the vibration cylinders 3 and prevent an abnormality in the human body from occurring and save on labor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic apparatus for removing air bubbles in ready-mixed concrete in a form during production of a secondary concrete product, and to a method therefor.

[0002]

2. Description of the Related Art In conventional air bubble elimination, a light urinal rod is manually operated, and a vibrating cylinder of the light urinal rod is repeatedly inserted into and pulled out of ready-mixed concrete a dozen or more times per mold. .

[0003]

The secondary products of concrete are small in quantity and varied in variety, and have various shapes. Therefore, when air bubbles are to be removed, it is necessary to manually operate and use the electric light rod according to the shape of the formwork. For this reason, the operator has vibration disease, back pain,
At present, they complain of shoulder pain and require a large number of people for the bubble removal process.

The present invention is an apparatus devised for the purpose of preventing abnormalities in the human body and saving labor.

[0005]

In order to achieve the above object,
The automatic air bubble eliminator of the present invention uses a plurality of light urinals instead of a large number of persons, and is mounted so that the position of each light urinal can be arbitrarily adjusted in order to correspond to all mold sizes. There is an automatic device in which a vibrating cylinder is inserted into ready-mixed concrete in a formwork while applying vibration so that air bubbles in the ready-mixed concrete escape along the vibrating cylinder.

[0006] The present apparatus has a plurality of generally used light urinals attached as vibrators.

In this apparatus, a plurality of light urinal rods can be moved forward and backward so as to correspond to all shapes and sizes of molds, and can be moved in the left-right direction. Further, the mutual pitch distance between a plurality of light urinal rods can be arbitrarily adjusted.

[0008] There are relatively many concrete secondary products in which the product shape is not vertical but has a slope. After inserting the vibrating cylinder of the light-duty electric rod vertically into this type of formwork, it hits the wall of the formwork halfway, so that the light-duty electric rod is adjusted to the inclination angle of the product, and the vibrating cylinder is It can be inserted and retracted inside.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a front view of the automatic bubble removing device, and shows a relationship with a sloped formwork. A formwork filled with ready-mixed concrete is placed directly below the bubble eliminator, and the position of the light-weight electric rod relative to the formwork is determined by the traveling motor (10). Perform left and right positioning.

3 and 4, in the case of a formwork with a slope, in order to adjust the slope frame to the slope of the formwork, the left and right side tilt motors (12) and the front and rear side tilt motors (13) are driven respectively. By tilting, all the lightning rods are fitted to the mold via the guide metal and guide shaft.

In FIG. 5, since there is a partition plate (16) in the mold, if the light electric rod is lowered as it is, the vibrating cylinder abuts on the partition plate (16) of the form, so that the light electric rod attached to each slider is removed. Pitch feed motor ▲ 14 ▼
By driving, the position is changed to a position that does not interfere with the partition plate (16), and preparation before insertion is completed as shown in FIG.

[0012] All the light poles attached to the upper and lower bases are activated, and the upper and lower bases are lowered by driving the upper and lower motors (15). The vibrating tube of the light electric rod is gradually inserted into the ready-mixed concrete in the form while vibrating, and bubbles in the ready-mixed concrete escape along the vibrating tube.

After a little time, the up and down motor (15)
The upper and lower bases are raised by driving, and the vibrating cylinder is pulled out of the ready-mixed concrete.

This completes one cycle. However, depending on the shape and size of the mold, the position of the light utility rod may be slightly shifted and the vibration cylinder may be inserted again.

[Brief description of the drawings]

FIG. 1 is a front view of an automatic air bubble removing device, showing a position when an inclined formwork is installed as an example.

FIG. 2 is a right side view of the automatic air bubble eliminator, showing a position where a sloped formwork is installed as an example.

FIG. 3 is a front view showing a state in which the automatic bubble removing device is inclined according to the partition gradient of the mold.

FIG. 4 is a right side view showing a state in which the automatic bubble removing device is tilted according to the gradient of the mold.

FIG. 5 is a partial state diagram showing the relationship between an automatic bubble eliminator, a sloped formwork, a product having a partition plate, and a light utility rod. In this drawing, since the light urinal rod is not adjusted to the pitch of the mold partitioning plate, if the light urinal rod is inserted as it is, the vibration cylinder interferes with the partition plate of the mold.

FIG. 6 is a partial state diagram showing a state in which the automatic air bubble eliminator is ready for insertion by adjusting the pitch of the light urinal rod to the pitch of the mold partition plate.
